4-8 BE1-50 Installation
NOTE
Be sure the relay case is hard-wired to earth ground with no smaller than 12 AWG copper
wire attached to the ground terminal on the rear of the relay case. When the relay is
configured in a system with other protective devices, it is recommended to use a
separate lead to the ground bus from each relay.
CONNECTIONS
Incorrect wiring may result in damage to the relay. Except for the ground wire, connections should be made
with minimum wire size of 14 AWG. For the ground wire, refer to the following note. Typical sensing input
connections are shown in Figures 4-10 through 4-13. Typical output connections are shown in Figures 4-14
and 4-15. Typical internal connections are shown in Figures 4-16 through 4-18.
Relay circuitry is connected to the case terminals by removable connection plugs (1 plug for 10-terminal
cases and 2 plugs for 20-terminal cases). Removal of the connection plug(s) opens the N.O. trip contact
circuits and shorts the N.C. trip contact circuits before opening the power and Sensing Circuits.
